The idea is that when the ignition is turned off, the empeg is supposed to turn itself off shortly thereafter. But sometimes this does not happen, due to the player app having crashed, or a hard disk failure. The result can be a run-down car battery the next morning.

So Hijack v517 now implements its own failsafe timer for power-off. If the player software fails to issue the power-off command within five seconds of the normal timeout (from config.ini), then Hijack will issue the command itself.
